ROHM presents new complex transistor DTDG series
ROHM has presented its new complex transistor DTDG series which is developed for the drive circuit of solenoids, motors and relays, integrating resistors and a zener diode. Zener diodes have the function of absorbing back electromotive force surge voltage from L-load to avoid the breakdown of the transistor by overload voltage. Therefore, an external protection diode in this case is not necessary. Input resistors are built-in to enable the direct drive by the control IC (DTDG23YP).
The DTDG series is available in different line-ups such as the MPT3 and the TSMT6 with a different range of voltage, IC, hFE and resistance.
